BSW7421
Description
The BSW7421 is a reflective SPDT RF switch that can be used in high power and good performance WLAN 802.11 a/b/g/n/ac/ax, DOCSIS 3.0/3.1 and Wireless munication applications. This device is packaged in Ro HS2-pliant with 1.5mm x 1.5mm x 0.5mm, 6-Lead UDFN package. It must be used with back side ground soldering. The BSW7421 has robust ESD protection circuits at all pins and temperature performance (operating temperature range : -40 to +105°C). This switch does not require blocking capacitors. If DC is presented at the RF port, add a blocking capacitor. This device also has a high linearity performance over all temperature range such as IIP3, IIP2. A functional block diagram is shown in Figure 1.
